Which photographer discovered Georgia O'Keeffe's abstract drawings in 1916?

Alfred Stieglitz discovered Georgia O'Keeffe's abstract drawings in 1916. He exhibited a group of her charcoal abstractions at his New York gallery, 291, after a friend sent the drawings to him without O'Keeffe's prior approval.

Stieglitz was already one of the most important promoters of modern art in the United States. His gallery introduced American audiences to European avant-garde artists, and his support gave O'Keeffe an early public platform. Their correspondence became a major part of their relationship.

Stieglitz and O'Keeffe married in 1924, although their relationship was complex and both maintained independent artistic lives. Stieglitz also photographed O'Keeffe extensively, creating hundreds of portraits over several decades. Their partnership connected painting, photography, gallery culture, and the development of American modernism.
